New Cosmological Solutions in Massive Gravity

, 2012
We find new, simple cosmological solutions with flat, open, and closed spatial geometries, contrary to the previous wisdom that only the open model is allowed.

Observational Constraints on Transverse Gravity: a Generalization of Unimodular Gravity

, 2010
We explore the hypothesis that the set of symmetries enjoyed by the theory that describes gravity is not the full group of diffeomorphisms Diff(M), as in General Relativity, but a maximal subgroup of it, TransverseDiff(M), with its elements having a ...

Dark energy and dark matter from nonlocal ghost-free gravity theory

, 2012
We suggest a class of generally covariant ghost-free nonlocal gravity models generating de Sitter or Anti-de Sitter background with an arbitrary value of the effective cosmological constant and featuring a mechanism of dark matter simulation.

Gomal Zam RCC Arch-Gravity Dam in Pakistan

Journal of Intelligent Construction
Gomal Zam Roller Compacted Concrete (RCC) Arch-Gravity Dam is up to now the only arch-type RCC dam in Pakistan. In the selection of dam axis and type, the local topographical and geological conditions were intelligently used to create the largest ...

Local precision nets for monitoring movements of faults and large engineering structures [PDF]

Along Bocono Fault were installed local high precision geodetic nets to observe the possible horizontal crustal deformations and movements. In the fault area there are few big structures which are also included in the mentioned investigation. In the near
